Description
Give the future athlete in your barn the start they deserve with Purina Ultium Growth Horse Formula, a nutrient-dense pelleted and extruded feed for weanlings, yearlings, two-year-olds, and the broodmares carrying and nursing them. Four years of Purina feeding trials across multiple foal crops shaped this formula, tracking growth curves, joint health, body condition, and activity to land on a growth ration that builds steadily rather than too fast. Fed with good hay or pasture, it delivers 15.5% protein, 9.5% fat, and a mineral package aimed squarely at bone and joint development.
Key Features
- Sustained Energy System: Calories come from fat, fermentable fiber, and soluble carbohydrates rather than starch alone, matching the elevated demands of growing horses and lactating mares.
- Targeted Nutrition Delivery System: Moves copper, zinc, calcium, and phosphorus to where they do the most good for long-bone and joint development.
- Outlast gastric support: Supports proper stomach pH and gastric comfort while supplying calcium for bone growth; a 4 lb meal gives a full serving.
- Amplify high-fat nugget: Fatty acids from vegetable oils, flaxseed, and rice bran hold condition on lactating mares and keep young horses blooming.
- Precise amino acid profile: 1.00% lysine, 0.48% methionine, and 0.55% threonine plus branched-chain amino acids for muscle development.
- Multiple fermentable fibers: Beet pulp and soy hulls support a developing hindgut with less sugar and starch than a traditional sweet feed.
Feeding Directions
Broodmares: feed a 1,000 lb mare about 5.25 lbs per day through the last 90 days of gestation and about 7.5 lbs per day while lactating, alongside a minimum of 12 lbs of hay (20 lbs for a lactating mare). Growing horses: weanlings, yearlings, and two-year-olds take roughly 6.25 to 8.35 lbs per day at 500 lbs of body weight and 6.75 to 8.5 lbs at 1,000 lbs, with the lower rate for moderate growth and the higher rate for more rapid growth. Start suckling foals within two weeks of birth at 1.0 lb per month of age per day. Never feed less than 0.35 lbs per 100 lbs of body weight for gestating mares, 0.50 lbs for lactating mares, or 0.75 lbs for growing horses, and never more than 0.5 lbs per 100 lbs in one meal. Change feeds gradually over 7 to 10 days and keep clean water and salt available.
Caution: Follow label directions. Feeding added selenium resulting in total diet levels in excess of 0.3 ppm is prohibited.
